To avoid electrical shock, turn off all electrical power to the heater if service is to be performed on a heater that is
equipped with an optional blower.
It is necessary to
KEEP

AND
CONTROL
COMPARTMENT
CLEAN
. In even the cleanest homes, lint and dust carried
by air moving through the heater will collect on parts of the heater. If allowed to become excessive, this lint and
dust will plug the air intakes of the burner and pilot. Excessive buildup at the burner intakes can cause improper
combustion of the gas with the production of carbon monoxide. Excessive lint and dust buildup around the burner
can become a fire hazard. The following maintenance program should be followed monthly or more often in areas
where dust or lint accumulated rapidly.
1. Turn the gas off at the shutoff valve in the gas line and allow the heater to cool.
2. Remove the heater’s front panel.
3. Use care to avoid striking the gas lines and carefully vacuum all dust and lint from the burner intakes, pilot
and inside the cabinet. If any gas lines are struck, carefully check each joint for leaks as defined in the

4. Replace the heater’s front panel.
5. Light the pilot and operate the heater according to instructions.

The pilot gas flow is not adjustable on this heater. Proper operation of the ODS (Oxygen Depletion Sensitive) Pilot
Safety System is dependent upon the pilot gas flow rate and any attempt to adjust this rate could cause the ODS
System to not operate correctly. It is very important that the pilot be kept clean and free of lint and dust. Should
the pilot flame show a yellow tip, clean the air intake in the pilot burner (see Figure 7). The pilot orifice spud is not
replaceable for this pilot. Should it become plugged, clean it only with forced air.

Each year, before the heater is used, the entire heater and control system should be inspected by a qualified
service person. Any service which requires disconnecting the gas supply line must be performed by a qualified
service person. If the heater is moved, even slightly, for any reason, the gas supply lines must be rechecked for
leaks immediately with a soap-water solution or a liquid gas leak detector. If leaks are found, turn the gas off at the
shutoff valve until all leaks are corrected.
